NOZZLE.

SPECIFICATION forming part of Letters Patent No. 713,670, dated November18, 1902. Application filed August 31, 1901. Serial No. 73,976, (Nomodel.)

To [tZZ whom, it may concern: Be it known that 1, CHARLES HERBERTOGUMPAUGH, a resident of Rochester, in the county of Monroe and State ofNew York,have

invented certain new and useful Improvements in Nozzles; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

The invention relates to nozzles for sprinwatering plants, and likepurposes, and has for its object to increase the efficiency and cheapenthe construction of such nozzles.

It consists in the construction herein described and pointed out.

In the accompanying drawings, Figure 1 is a central longitudinal sectionof the nozzle. Fig. 2 is a plan. Fig. 3 is a perspective of thenozzle-base.

Numeral 1 denotes a milled flange of a noz-' zle-base 2, having interiorscrew-threads for attachment to a coupling or pipe.

3 denotes a shoulder within the barrelof the base to support an elasticgasket in usual manner. Above this shoulder is a liquidsupply space 4,which is practically a con tinuation of a supply-pipe (not shown) andcommunicates with a vortex-chamber 5 by means of obliquely-arrangedpassages 6, extending through the base, near its upper end, asillustrated.

7 indicates rudimentary grooves or channels formed in the upper edge ofthe base adjacent the passages 6 and in communication therewith. V

8 denotes a tip or central extension of the base. Said extension isfrusto-conical in form and has its small end fixed to the base. Itishollow, and its interior communicates with the supply-space 4 by aperforation or exit 9. Said perforation does not lead into thevortexchamber, but communicates directly with the atmosphere.

The tip S,independently of the fact that it is so styled and of itsbeing an extension of the base, is a body occupying the interior of thechamber 5 below the exit 14 and below rim 16, that is in a differentplane, whereby said chamber is contracted between its ends, and wherebya free transverse space is left between the rim and its exit-opening 14and saidbody, with the effect that the discharge is more effectuallyspread and sprayed.

1O denotes a cap which may be screwed upon the base and against theflange 1 or against a gasket contiguous said flange. The exteriorscrew-thread 11 of the base preferably does not extend to the flange,but is separated therefrom by a plain surface 12.

13 denotes a plain surface between the screw-thread 11 and the end ofthe barrel of the base.

14 denotes a central discharge-opening in the concavo-convex top of thecap, and 15 is a shallow groove or channel situated within theprojecting rim of the cap-top. This channel is in approximately the sameplane as the wide end of the tip or base extension 8. The base extension8 flares outwardly and extends to the vicinity of the opening 14 andnear the wall of the cap. The diameter of its larger or free end isgreater than that of the opening, whereby an annular space or exittransverse to the axis of opening 14 is provided. The capacity of thevortex-chamber is increased by the contraction of base extension 8toward its fixed end and by the groove 15, situated oppositely to saidcontracted end of the base extension.

The discharge-opening 14 of the cap has a diameter smaller than that ofthe large end of the tip, which end is situated near the opening whenthe parts are assembled for use, and thereby provides a circumferentialdischarge or exit 17. The dimension of this exit can in practice bevaried by adjusting the cap on the base.

In operation a liquid forced into the space 4 from a pipe or hoseescapes mainly through the oblique passages 6 into the vortex-chamber ina direction approximately tangential to the wall of said chamber,withthe effect to impart a gyratory motion about the extension 8 and in thechannel 15 and in the exit 17 between the extension and cap. Waterescapes through this exit all around in directions approximatelytangential to the convex face of the cap and transversely of the lengthof the nozzle. The pressure will also force Water through the centralexit9, which may be made to rise to a height of ten or more feet, whilethe transverse spray can be made to cover a space forty or more feet indiameter. The whirling or gyratory movement of the liquid in thevortex-chamber is aided by the channels 7 and also by the extension 8,whereby a channel 18 is produced. The channel 15 extends-thevortex-chamber laterally adjacent the large end of said tip 8 andprovides for a freer movement of the liquid. The tip by its centralsituation and apart from the special form shown cooperates with theoblique passages 6 to produce a vortex. In the particular form preferredits larger end separates the vortex into two parts, one of whichcommunicates directly with the inlets and the other with the outlet, andthereby obviates cross-currents.

If in use the nozzle be pointed directly upwardly, the central jet ofliquid discharged from the exit 9 will fall about the nozzle itself.When the nozzle is directed horizontally, or approximately so, thecentral jet can be utilized to sprinkle an excess of liquid on aparticular spot, as on a plant situated in a lawn.

The extension and cap,combined with other parts, as set forth, produce aflaring discharge of great uniformity and with an ornamental effect, andparticularly in connection with the discharge from the central tip 8.This discharge or jet does not communicafe with the vortex-chamber, andis therefore not hindered nor checked by the water in said chamber. Theextension or tip 8, which occupies the vortex center contributes both tothe perfection of the vortex and protect-s the central jet. By means ofits flaring month, situated just within the cap adjacent the opening 14,the extension-tip 8 also insures that the central jet shall not beinterfered with by cross-currents from the main vertical discharge.

Having thus described my invention, what I claim as new,and desire tosecure by Letters Patent, is

1. Inanozzle,the combination ofabase having an internal thread, holesextending in approximately tangential direction through the base abovethe internal thread, and a frustoconical base extension, said extensionflaring outwardlyfrom the upper surface of the base.

2. In a nozzle, a base having an extension, and a cap with a perforatedtop attached to the base, the perforation in the cap being of lessdiameter than the greatest width of the extension, said extensionflaring outwardly from the base to near the perforation and within thecap.

3. In a nozzle,a cap having a chamber 5 and a body situated in saidchamber between its ends whereby the space in the chamber is contractedlaterally, said chamber having a single unobstructed central outlet 14at one end of the cap and a laterally free space between said body andthe edge of the cap about the outlet, and having two or more inlets 6 atthe other end, said body having its periphery immediately adjacent theoutlet larger than the same thereby projecting laterally beyond theinner edge of the cap-outlet to provide an annular and approximatelyhorizontal exit 17.

4. In anozzle,a cap havinga chamber 5 contracted between its ends,and asingle central exit 14 at one end, and two or more inlets at the otherend, said contracted part surrounding a frusto-conical piece having itslongest transverse diameter close to said opening.

5. In a nozzle, a chambered cap having a central unobstructeddischarge-opening at one end, and containing a body extending from theother end of the cap-chamber to a plane in close proximity to theopening and in a different plane entirely within the caprim, said bodyhaving a transverse diameter greater than the opening, whereby a freetransverse space is provided next the rim and opening, and an exit 9opening into said transverse space.

6. In a nozzle, a chambered cap having a central unobstructeddischarge-opening at one end, and containing a piece extending from theother end of the cap-chamber to a plane in close proximity to and belowthe opening and withinthe cap, said piece having a transverse diametergreater than the opening at the outer end of said piece and at its innerfixed end a transverse diameter less than that of the said opening.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
